Be it'kIlOWnthat'I yJurns'Bnnot fi, a citizen of the French Republic,and residing in :application in France Sept. 3, 1919, No.- 10

with a metallic closing means, as introduced follows:

Paris,- France," 47 Rue Blanche, havemi-nvented certaln new and usefulImprovements Volatile Products (for which I have filed an 512,647,) ofwhich the following is a complete specification.

The chloride of ethyl bottles, provided by the inventor in 1891, have adisadvantage which it is dilficult to remedy, this drawback consistingin the too frequent obstruction of the capillary orifice so that theoperator when using the bottle finds that he hasin hand a flask whichdoesnot work. a V

The reasons for such obstruction areas 1 Therubber from the plug,whentheftemperature falls,

to pass into the capillary canal and obstruct the same. a v (2') Therubber is attacked more or. less by the chloride of ethyl, a softens,"disintegrates and particles thereof may be sucked up and also causechoking of the capillary canal. Y i

According to the present invention thesedefects have been remedied byplacingthe capillary canal or duct under protection from all contactwith the india-rubber. To

.- that end the rubber washer is lined with a plastic non-poroussubstance not sensitive to the attack of chloride of ethyl and notreleasing or throwing ofi any dust whichmay consist for example'of asheet of celophany, colophonium or gelatine' rendered supple by theaddition of a "certain amountnof glycerine or any other substancepossessing canal. 1

In order to carry out the -inventionlthere is placed upon therubber'washer I a'rpro- 'tective washer 7 which'may'be madc ot celophanyor gelatine made supple with glyeerine, or. other suitable substance.The;-

said washer 7 will howe'verbe preferably I made of tin. The whole bodythus formed is placed in the'bottomfof the cap "onstopper 3 which is soscrewed upon the neck of the bottle that the capillary orifice 5 0 17the said bottle may only be "in jecting washer 7. it

V. As will be clearly understoodthe rubber 7 of the washer may bereplaced in both cases by any otherplastic substance. :The prOtectivewasher 7 as well as the cork cylinder 2 may be made of any. plasticsubstance not:

subject to attack by the liquid contained in i 100 ever, being, in the-"preferredformf of'con-f Y CIT- In the structural form according to Fig;

ures 4 to 6 the cork cylinder may be replaced by a block in the form ofa truncated cone the small base of which would be in contact with thecapillary'hole; Y w

The contact surface of the protective washer or'of the cork cylinderWltlitll rubbeig may be provided with asperities engag;

ing the recesses made in the rubber.

The invention may also be realized by 1101- lowing out therubber intoasmall recess in which there is placed an inverted truncated cone oicork, gelatine, celophany, or other suitable substance, such as tin, thelarge base of which would be in contact with the capillary orifice, theelasticity oflthc closure be-" in; obtained in every-case bythe rubberWasher which is' protected against attack, its contact'vvith thecapillary orifice being'prevented by the protective organ.
